MAX1112 - +5V、低功耗、多通道、串行8位ADC - 数据转换器和采样-保持电路 - 功耗最低的8位、4/8通道ADC，内置基准 - 美信半导体
The MAX1112/MAX1113 low-power, 8-bit, 8-channel analog-to-digital converters (ADCs) feature an internaltrack/hold, voltage reference, clock, and serial interface.They operate from a single 4.5V to 5.5V supplyand consume only 135μA while sampling at rates up to50ksps. The MAX1112's 8 analog inputs and theMAX1113's 4 analog inputs are software-configurable,allowing unipolar/bipolar and single-ended/differentialoperation.
Successive-approximation conversions are performedusing either the internal clock or an external serial-interfaceclock. The full-scale analog input range is determinedby the 4.096V internal reference, or by anexternally applied reference ranging from 1V to VDD.The 4-wire serial interface is compatible with the SPI™,QSPI™, and MICROWIRE™ serial-interface standards.A serial-strobe output provides the end-of-conversionsignal for interrupt-driven processors.
The MAX1112/MAX1113 have a software-programmable,2µA automatic power-down mode to minimizepower consumption. Using power-down, the supplycurrent is reduced to 13µA at 1ksps, and only 82µA at10ksps. Power-down can also be controlled using theactive-low SHDN input pin. Accessing the serial interface automaticallypowers up the device.
The MAX1112 is available in a 20-pin SSOP package.The MAX1113 is available in a small 16-pin QSOPpackage.
